A cold state engine or an apparatus utilising air heat energy to output work, refrigeration and water, comprises of vaporiser, high pressure expander, high pressure working fluid pump, ambient heat exchanger, circulation pump, generator, pipes, valves, sensors which are operatively interconnected together, using single or two atom gases as a working substance, based on methods of cryogenic working fluid thermodynamic - refrigeration cycle and frost-free two stage cycle heat exchange technology wherein the single fill of cryogenic working fluid or high pressure gas as initial power to start the cycle, absorbs air thermal energy vaporise into high pressure gas which then propels the expander to turn and output mechanical work and refrigeration capacity, the air heat exchanger outputs refrigeration condensation and dry air. The present invention provides methods and apparatus to utilise the heat energy of environmental fluid to produce power, fresh water, and refrigeration. |
